Super Meat Boy

Tried out the Steam for Mac forum with horrible results, but Gabe N seems to think super meat boy fans are the best fans so I'll just pose my questions here as well...

My girlfriend just got a new Mac, what games should I get her from Steam? Don't say tf2, or any other f2p, pay4addiction games. Leave those to me.

Lately she has enjoyed numerous iOS games like Where's My Water, Angry Birds (especially the new Star Wars ones with the planets and gravity stuff), Robot Unicorn Attack, Cut the Rope, and dozens of others I don't even know about. She also enjoys random PS1 games I have like Crash Team Racing. Games I have played recently which she's stated she enjoys watching are Super Meat Boy, Superbrothers Sword and Sworcery, The Cave, and Team Fortress 2.

(Games I've been playing which she says bore her to tears are FTL, and Civ V.)

If she's into point n' click, she would probably enjoy Machinarium and Botanicula. They're really beautiful and have amazing atmosphere, especially Machinarium. I think Cave Story+ and Braid are easy to appreciate as well. Cave Story+ has got cute characters and nice visuals, and Braid is a piece of art. Pretty obivous choises but here's my two cents.

Sonic Generation, Mini Ninjas and Skyrim are all good games I'm sure, but this is Mac games we're talking about. I tried to think other games that might be worth looking into, and if The Binding of Isaac is too disgusting for her, it might be worth checking out. It's quite hard and there's a remake coming but it probably won't be released until next year, and the original isn't even that expensive. Bastion is really cool too.
